To all whom it may concern-.-

Be it known that I, HARLEY A; WVAL'DEm;

a citizen of the United States, residing. at WVest Terre Haute, in the county 'ofVigo and State of Indiana, have invented certain new and useful Improvements in Grate Dumping and Handling Apparatus, of

which the following is a-specifications-z This invention compr'ehends generally improvements in that class of inventions known. as furnaces and more partlcularly relates to g a grate dumplng and ash handllngapparatus.

It is the primary aim and object-of this invention to provide an apparatus of the above mentioned character designed to be associated with a puddling or other type of furnace, improved means being employed for movably mounting the grates within the body of the furnace while acting in con junction therewith is improved manually operable means for ralsing and lowering the grate to permit of the dumping of the ashes therefrom at the time it is desired to start a new fire.

As an additional and equally important ob ect this invention contemplates the'pro- -vision of a device of the above mentioned' characterv whereinthe meansfor raising and lowering the grates or swinging them vertically is of improved construction embodying-generally a manually operable lever po-- sitionedexteriorly of the body of the fur.- nace and operably connected as by flexible elements with the grates, improved means. being also employed in conjunction with the levers for releasably locking the levers to consequently releasa'bly maintain. the grates in a raisedoperative position.

The invention also embraces the provision"v of an apparatus of the abovev mentioned character wherein the door whichestablishes access to theash pit jo'rbox is of improved construction being also mounted in an im:

proved manner so to act as a deflector or chute for the ashes at the time the grates are dumped to consequently insure of the dis charge of the ashesinto an ash pit adapted to be positioned in the ground and in proximity to andbeneath the outer, end of the chute, door. 7 4

More specific objects of this invention con sist in the provision ofan apparatus of'the above mentloned character wherein. the rates proper are of improved:constructlon;V to provide lmproved means for operating and holdingthe door in either of its adjusted positions: and to provide means onthe body of the furnace for embracing the (tr-or when in lts ooen and closed position. Among the other a ms and ob ects ofthev invention maybe recited the provision of a device 101' apparatus of the above men .tioneol' character with av-iew to compactness'wherein thennmber of parts are comparatively few, the constructionsimnle, the

cost of production low and the efliciency- 1 high. 7

Other objects, as well as the nature, char acteristic features and scope of this invention Wlll be more readily apparent from the following description taken-in connection with the .raccompanying drawings and pointed out in the claims, forminga part of thisspecification. V V

The invention is clearly illustrated inthe accompanying drawings, in" which:

door and for holding the door in the desired position of adjustment. Y I

bimilar characters of reference are em-,

ployed in all of the above described views, to indicate corresponding parts. 7 Referring now, more particularly, to the accom anying drawin s there isillustrated; --a furnace includlng a body 1 which ma be.

of a rectangular configuration while arranged medially of the ends thereof is a vertically and transversely disposed partition 2 in turn carrying on one face a transversely disposed beam and also carried by the same face are pairs of laterally projecting hooks 1 positioned in spaced relation beneath the beam 3 for a purpose which, will presently appear.

liith a View toward providing the improved grates each maybe said to consist of a rectangular frame 5 the end portions of which are pro *ided with opposed longitudinally aliningopenings 6 in which is removably fitted the ends of grate bars 7. Supports 8"of angular configuration are connected to the forward end bars of the grate and removably receive therein latching bars 9 which act to releasably hold the grate bars against displacement yet at the same time permit of the removal of the grate bars when the latter are injured.

Spaced pairs of engaging elements such as eyes 10 extend from the inner or rear end bars of the grates 5 and are engaged with the adjacent hooks 4, this arrangement serving as a means for swingably mounting the grates vertically of the body of the furnace, the rear end portions of the grates being positioned beneath the beam 3 and when in a raised horizontal position these grates divide the forward end of the furnace into a fire box 11 and anash pit or box 12, as is apparent.

In order to raise and lower the grates improved operating means has been employed and in reducing this feature of the invention to practice operating levers 13 and 14 have their inner ends swingably connected by means of a pintle 15 to the front face of the body of the furnace, the levers being positioned parallel to the front face and designed for vertical swinging movement. Suitable flexible elements such as chains 16 are employed and have their outer ends connected to the levers and their main portions trained about pulley wheels 17 operably mounted on the front face of the body of the furnace and also trained through openings or passages 18 provided in the front end of the furnace, the opposite ends of the chains being connected to plugs 19 which in turn have depending therefrom hooks 20 designed for removable engagement with eyes 21 which rise from the upper edge of the front end bar of each of the grates.

' To protect the operating means the fire box of the furnace is provided with a bevel front wall construction being provided by the provision of a partition 22 positioned vertically and transversely of the firebox and in closely spaced relation to the front wall. A cross bar or beam 23 closes the space between the partition and the front wall and in turn is provided with beveled openings 24 for receiving the plugs.

For the purpose of releasably latching the levers in either of their adjusted positions a platelike bracket 25 is employed and connected by suitable fastening means 26 to one side wall of the furnace and extends laterally from the forward or front wall, the extending portion being provided with spaced vertically arranged slots 27 through which the outer projecting portions of the levers 13 and let are arranged. In addition, this plate is provided with transverse bores or passage ways 28 and-29 positioned near the upper and lower ends of the slots and intersecting the same, the passage ways opening at the marginal edges of the plate brackets being designed to removably receive locking pins 30 flexibly connected to the body of the furnace asby chains 31.

As intimated improved means has been provided for establishing access to the ash pit or box and in reducing this feature of theinvention to practice the lower portion of the end wall of the furnace immediately adjacent the ash pit is provided with an opening 32, thisopening being preferably provided by removing the entire lower portion of the said front wall of the furnace.

A door 33 is designed to removably close the opening and consists of a plate-like body from the opposite sides of which and slightly beneath the center extend opposed trunnions 34: which are journaled in brackets 35 mounted on the forward edges of the sides of'thefurnace body as indicated, this arrangement permitting of a vertical swinging of the door. Stop strips 36 are respectively carried by the front side walls of the fur new body and near the upper edge of the opening at the sides of the opening extend-- the rear edge is inclined toward the bottom so as not to interfere with the removal of ashes therefrom. Opposed vertically arranged supporting bars are carried by the inner surface of the side walls of the ash pit and arranged in proximity to the forward edge thereof and provided with diagonally cutnpper ends 39 for a purpose which I 'will presently appear.

In order to operate the door 33 so that it will serve as a deflector or chute to facilitate the discharge of ashes received thereupon into a main receiving ash pit adapted .to be positioned beneath the projecting end thereof, a handle 40 is connected to the 1 elongated portion of one of the trunnions 34 to facilitate the swinging of the door indental displacement.

In releasably latching the lever 40 in either of its adjusted positions the latch bar 41 is swingably connected as at 42 to one side of the furnace body and is provided near its outer end with spaced laterally extending stop plugs 42 designed to be arranged against the lever 40 so as to prevent swinging thereof. As noted upon reference to Fig. 2 the lever 40 is provided on opposite sides with recesses or notches 4A and 45, the outer lug 48 being engageable with the inner recess or notch 45 to lock the door closed. It is apparent that the lug may be swung out of engagement with the recessand the bar 41 raised to permit of swinging of the lever so as to move the door into open posi-' tion while subsequently the bar may be swung downwardly so that the inner lugs 43 will swing into engagement with the notch or recess 44, thereby locking the door in an open position so that it will serve in the capacity of a chute or deflector.

Access is had to the fire box through the instrumentality of a fire door 46. This door is mounted on the side wall of the furnace body and of course causes the usual door opening.

In use, when it is desired to dump the ashes from the grates to permit of the building of a new fire, the handle 40 is swung so 7 as to move the door into open inclined position whereupon the locking pins 30 are disengaged from the plate-like brackets 25 to permit of the levers l3 and 14 moving up wardly under action of the weight on the grates 5, the lower movement of the grates being limited by the door but as the grates are inclined the ashes will slide thereover and be received upon the inclined door which acts as a deflector for in turn discharging the material into the main receiving ash pit (not shown). lVhen all of the coal or ashes have been removed the levers 13 and 14 are swung downwardly and by reason of the flexible connection, namely the chains 16, the grates will be drawn into a raised operative position to permit of the building of a new fire.

It is believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise, it is believed that the advantages of the invention will be readily apparent.

Still further embodiments of the invention than those herein especially defined may be resorted to as conditionsfor preference may dictate, as may: be inkeepingwith the hereto appendedclaims.
